文章开头处有冒号
Have you ever experienced anything like this: you were to call a good friend, but you couldn't recall the telephone number? You were shopping in the grocery store for your mother, but you couldn't remember exactly what you were expected to get for her. Even when things have been learned well in our memory, we find that we cannot recall them when we need them. It may be that ten minutes later, or the next day, our memory will tell us what these things were, but it is true that the memory is not always perfect. Of course it is possible to train ourselves to remember things better. This usually involves repeating the facts to ourselves, or even writing them a few times until they are easily remembered. Memory allows us to remember facts, see them in the light of new information, and make decisions that are important to us. It would be nice if it were always perfect, and it will be nice when we know even more about how memory works on a biological and mental basis.
你有没有经历过这样的事情：你正要给一个朋友打电话，却记不起电话号码了。你去杂货店替你妈妈买样东西，到了那儿却记不起来她让你买什么。即便是一些我们记得滚瓜烂熟的东西，要用的时候也会想不起来。也许10分钟后，也许第二天，我们的记忆会告诉我们这些是什么。不过，千真万确的是，我们的记忆并不总是完美的。当然，通过训练可以提高我们的记忆力。训练的方法通常包括重复要记的事实。甚至把它们一遍一遍地写下来，直到轻而易举地记住。 记忆力使得我们能记住事实，结合新的信息来分析，从而做出对我们重要的决定。假如记忆总是完美无缺的，那该多好啊！如果我们能更多地了解记忆的生理和心理机制，那该多好啊！ ——译文来自: mannywang927
